r COKE OVEN GAS CONNECTION i Application filed July 8,

This invention relates in general to improvements ofgeneral utilityin the coking retort oven art and more particularly to improvements in the connections between the for t lie'heating walls. T Objects of the invention arethe provision of aeonnection,fthrough which the fuel gas may flow from the longitudinally. extending gas mama) the gas guns of the individual transversely extending heating walls of a :battery of coking retort ovens, that will accommodate the difierences resulting in temperature differentials or longitudinal vertical'andtransverse expansion and contraction of the battery or its associated parts, and therebyxprevent straining of the connections and leakages through the joints and the valves, the provision'of a flexible connection which is inexpensive, lasting, and readily .and easily assembled between the gas main and gas gun, and such otherobjects and advantages of the invention as may be; found to obtain in the structure hereinafter set forth and claimed. 1

[Referring to the drawi1igs,thereis shown a portion of the front of a coke oven battery A of theby-pro'duct'type,which embodiesin its construction a plurality of, coking chambers" 1 "versely ofth'e battery, and havingthe usual transversely extending alternating heating walls 2 intermediate adjacent. coking chambers, said heating wall'si'being provided withthe usual vertical fiameffiue's 3 for-generating; heat to coke'thechar'ges of coal in the coking arranged side by side, andrunningtrans- 4&

chambers. ,Theheatingwalls extend vertical 7 outer fa'cecf whichisbraced by a pair of verbattery below the level of the coking cham 'bers" andheating walls, communicate with the heating. fines of their companion heating walls by means ofthe usual short ducts or ports 5 and function to take up the heat of the V gases outflowing from theheating walls and impart such heat to the outside air in-'fiow-.

gas burning inthe heatingfluesinwhich combustion is taking place. Q a e The inlets to the heating fiiies or'fiame flues located at their respective bottoms and at .1 ,iDg'thrOugh the regeneratorsto the heating fines to augment thefltuhe temperature of the each inlet th'ereis provided a shortfuel gas duct 6 equippedwith a suitable gas nozzle 7,

through which the inflowi'ng fuel gas passes into the heatingflues. Extendingtransverselyof the batteryfrom the opposite sides of the coking planter battery are gas channels 8, there beinga' pair of such .channelsan In its present embodiment, the invention is ranged approximately end to end for each Communicating with the inlets of the gas channels on opposite sides of the coke oven battery aregas guns 13; the series of gas guns 13 on each, side of the battery are supi plied with fuel gas from the usual fuelgas main 14 extending longitudinally along each side of the battery. Connected with said main 14 is a series of supply pipes 15 respectively leading to branch pipes or conduits 16 communicably connected with their respective gas guns 13 by a conduit 17 coupled at 18 to an inlet 19 of the gas gun. In each of the supply pipes 15 is provided a reversing gas cook 21 moved by an operating lever 22 which is connected with an operating rod 28, common to the series of reversing gas cocks, by clamps 24:. In each of the branch pipes or conduits 16 is provided a regulating cock 25, which regulates the amount of gas flowing therethrough. By reason of the fluctuation in temperature of the battery these pipes and the valves contained therein have been subject to strains causing the joints to weaken and at times to leak. In order to prevent such strains and to compensate for temperature differentials and the expansion and contraction of the plant in longitudinal, vertical and transverse directions of the battery, there is provided a flexible conduit between the gas main and the individual gas guns. As shown in the present instance, the conduit 17, consists of a metallic pipe 26, coupled at 27 to reinforced metallic flexible hose or conduit 28 which is coupled at 29 to the inlet 19 by coupling 18. The reinforced metallic hose or conduit advantageously may be of the usual kind for conveying fluids under pressure which has been reinforced or armored by curvilinear metal such as by laminations or windings of metal on the outer surface, or on the inner surface, or embedded in material forming the hose or conduit. Such a flexible connection provides a gas tight communication between the branch pipe 16 and the gas gun 13, and is capable of accommodating any temperature difierentials or longitudinal,vertical or transverse expansion or contraction of thebattery or associated elements resulting from fluctuations in temperatures 'andprevents leakages resulting from straining of the parts by reason of temperature differentials and fluctuations or from slight irregularities in spacing or misfitting of the conduits and their couplings.

The invention as hereinabove set forth is embodied in a particular form of construction and including a rigid metallic gas-gun terminating adjacent the external surface of the masonry structure; and a gas main mounted externally of said oven-structure for feeding fuel gas to said gas conduits, a plurality of reversing gas valves each individual to one of said gas-guns for controlling gas flow thereto from said gas main and a reversing means common to a plurality of said revers ing valves; of a plurality of gas conducting means communicably connecting said reversing valves with the gas conduits, each of the gas conducting means comprising a flexible connection between the reversing valves and the gas-guns adapted to yield when said gas conducting means is subjected to thrusts, and to accommodate creeping of said gas conduits lengthwise of said row due to expansion of said masonry-structure.

2. Thecombination with a coking retortoven masonry-structure comprising a coking chamber, a heating wall therefor disposed laterally thereof and having combustion chamber-means therein; a gas conduit extending from the exterior of the oven into the masonry-structure of said heating wall and communicating with said combustion chamber-means, said conduit being permanently arranged within the masonry-structure in fixed relationship with said heating wall and including a metal end section terminating adjacent the external surface of the masonrystructure; and a gas main mounted externally of said retort oven for feeding fuel gas to said gas conduit: of gas conducting means communicably connecting said gas main with said gas conduit comprising a flexible connection between the gas main and the metal end section adapted to yield when the gas conductingmeans is subjected to thrusts, and to accommodate creeping of said gas conduit laterally of the coking chamber and heating wall due to expansion of the masonry-structure.

3. The combination with a coking retortoven masonry-structure comprising a coking chamber, a heating wall therefor disposed laterally thereof and having combustion chamber-means therein; a gas conduit extending from the exterior of the oven into the masonry-structure of said heating wall and communicating with said combustion chambermeans, said conduit being permanently arranged within the masonry-structure in fixed relationship with said heating wall and including a metal end section terminating adjacent the external surface of the masonrystructure; and a gas main mounted externally of said retort-oven for feeding fuel gas to said gas conduit: of gas conducting-means communicably connecting said gas main with said gas conduit comprising a flexible metaland the metal end section adapted to yield 1 when the gas conducting-means is subjected tothrusts, and to accommodate creeping of said gas conduit laterally of the coking chamher and heating Wall due to expansion of the 5 masonry-structure.

Inwitness whereof I have hereunto set my hand.
